l specification.

My present invention relates to certain im provements which I have made more particularly to my former patent, No. 517,550, dated April 3, 1894, but is not coniined to a construction such as shown in that patent. The particular improvements which I have made and will hereinafter explain appertain to simplicity of construction, reliability of operation, and more eifectually preventing what is called water-hammer in this class of articles. In previous attempts to overcome the pounding or water-hammer,77 as it is called, various devices have been made, butas far as my information extends have not been entirely eifectual for the purpose.

Referring to the drawings, like letters of reference indicating corresponding parts, Figure l is a sectional elevation of my present device. Fig. 2 is a side elevation of the main valve. Fig. 3 is a side elevation of the auxiliary valve. Fig. 4 represents the auxiliary valve in section.

My present device embodies a coperative action of two separate valves, and, furthermore, the parts of each Valve are so constructed as to be substantially independent of each other, thereby insuring against the wearing of the parts to interfere with the practical and continued operation desired to be obtained.

In the drawings, A represents the shell or body of the faucet; B, the upper section of the shell, which is secured to the main bodyA by the thread B'. The main valve is represented by h' and its stem by b. This valve is supported by the annular frame ct, which by a cross-section furnishes a support to the said valve-stem. This frame ct rests upon the shoulder A', which is formed upon the interior of the shell. Beneath .the frame ot or main valve b'.

a is placed another packing-ringo. On the top of this is placed the annular piece e, the bottom resting upon the top of the packing c'. This piece is formed to exactly iit the interior of theV shell, and it is also formed cupshaped-that is, with the interior projection e', through which passes the short piston or stem CZ, which is connected atit-s lower end d4 with the top ofthe main-valve stem, as shown in Figs. l and 2. This projection e of the piece e supports the said piston d and also the spiral sprin g d5, which is placed around it and under the cap of said piston ol and which is indicated by d2. Above this part already described is placed the usual screw or threaded stem f for operating the valve mechanism, as will hereinafter be more particularly described. Any of the wellknown means for operating a valvefaucet from the top, as by screw or cam or levers, may be employed in this construction. The auxiliary valve is placed nearl the bottom within the shell A, as shown in Fig. l, h3 being the valve proper and h representing the stem. 7L' represents the cap upon the top of the stem. This valve and stem are supported by the frame g,whicl1 is screwed into the lower part of the shell, as shown at g. This valve is also provided with the spring 71,4, which rests upon the upper part of the frame g and beneath the cap-piece 7L. Fig. 4 represents the method of forming the valve-stein h, it having the sides h2 hollowed out for the purpose of admitting the fluid to the chamber above. `It will thus be seen that in this device we have simply the main shell A, with its top l5; that the lower valve and its frame are secured within the bottom of the shell; that above this, supported and prop- 4erly packed, is the main valve; above the frame supporting the main valve is placed the operative parts for moving the valve mechanism; the interior of the shell is plain, inexpensive to make, and cannot easily get out of repair.

Having now explained the general .parts of the invention, I will describe its mode of 0peration.

When the threaded screwf is turned down upon the head or cap d2 of the piston d, it is of course depressed, and the valve Zi is open downward. The bottom of this valve rests IOO upon the top of the cap 71, of the valve-stem h of the secondary valve. The downward movement of the main valve consequently 'depresses the secondary valve h3, and part h2, which is eut out of the body ot the stem h, is forced downward, so that the tluid from beneath can pass up and enter the chamber above. This will be understood by reference to Fig. 4. The fluid passing upward will enter the chamber formed in the frame (t and will be discharged through the lateral openings d2 in said frame to the spout or delivery. It will be observed that the uid surroundingr the main-valve stem Z) within the chamber and within the shell cannot flow upward on account of the packing-ring c', which exactly tits the interior surface ot the annular shell. In order to prevent any tluid passing` upward by the side of the piston d, I form midway of its length a depression for the packing of the steun-Which is represented in Fig. l by d. It will be observed also that in the movement ot this piston d the packing-ring d will always be within the raised projection c of the cup part e. When the threaded screw f is released, it will be thrown upward by the pressure of the spring d5 and the main valve b' will be forced into position, the pressure of the water upon the bottom of the valve ZJ also aiding its closing. As the' upper valve is closed, the auxiliary valve h3, with its stem 7i, ascends, but does not entirely close. Thus the pressure is equalized throughout lthe shell, and the .fluid serves as a cushion to the operation of the two valves in connection with each other. As there is no jar or shock when the main valve is closed, there is no noise or pounding or water-hammer, and the wearing of the parts is thereby prevented.

.In case it is necessary to take the main valve from the shell at any time it can readily be done without turning oft the water from the pipe or in any manner lessening the pressure, for it is obvious that when the top of the shell B is removed from the main shell A the frame d and all the contiguous parts can be readily removed through the top. When this is done, the auxiliary valve will be released and will be thrown upward by the force of the Water as well as by the spiral spring h4, which is usually used in connection with it, and the iiow of fluid will be at once stopped. When the main valve and parts are replaced, the original condition and relation ot the two Valves to each other and to the operation ot` the whole device will be at once resumed.

For convenience the piston d is formed at its lower end as shown in Figs. l and 2, and the upper end of the main-valve stem b is also formed as represented in said igures. The lower part of the piston, as represented by d4, slides in and is hooked or locked to the top of stem b. When the frame d and the contiguous parts are removed from the shell, the lowerend of the piston d can be 4readily unhooked and taken out through the cupring e. The opening through the upper end ot the frame d is made considerably larger than the diameter of the piston d. Consequently when it is desired to attach the parts together the piston d is placed in the cup part eand is hooked upon the top of the valvestem b, sufficient lateral movement of the cup part e being allowed by the opening in the top ot' frame d. After being connected together the cup part c is brought directly in line with the outside of the frame d and its packing c' and is held firmly in place within the shell. The upper part of the shell B by its shoulder presses upon the cup part e and forces it tightly against the packing c', which is placed upon the top ot' the annular frame d. Thus all of the parts are firmly held in place and a perfect fluid-tight separation is made between the frame d and the upper part of the interior of the shell. The method of attaching these parts together is represented in Eig. 2, the dotted line on theright representing the movement of the cup part e upon the packing c in the act of hooking or securing the lower end of the stem CZ to the top of the main-valve stem b. Ot course the valve-stem b and the piston dinight be made of one piece of metal. It this were done, it would be necessary to provide some means for removing the cap d2 in order to take the valvel and stem out of its frame. For convenience of use I prefer the form represented in the drawings. It is also preferable because by this means all the parts are securely locked together and held without the aid of screws or screw-threads of any kind, and consequently the parts are positive in their action and cannot become loose by use or wear.

As heretofore suggested, in this construction lthe lower valve operates to partially cut oft the supply of water to the upper or main valve, so that in the closing of the same the direct pressure is greatly decreased by the operation of the lower valve. The construction of the main valve also aids in its coming to its seat gradually instead of with a shock, as in the usual constructions for this purpose. The combination, with the mainvalve chamber, of the packing-disk d is so constructed as to afford a guide for the Inotive stem or piston d and no water or Huid can pass above the main valve chamber, thereby avoiding the escape of any fluid into the passages above the valve-chamber and obviating the necessity of any stuffingbox or packing around the actuating-stem of the apparatus. This is an important part of my present invention. In the construction shown in the drawings the lower or auxiliary valve consists of a plug or frame g, provided with threads and adapted to screw into a partition in the bottom of the shell or chamber from which the fluid is to be discharged, as already stated, and said plug or frame is further provided with a passage through its center to admit the introduction of a valvestem having the valve h3 at its lower end,

IOO

the said valve-stem being' so constructed as to allow the water to pass freely through the said plug or frame g. Vhen the stem is pushed to its lower point, it will partially cut off the supply of water through said plug by its vertical upward movement, and will, further, totally cut olf said supply through the plug when it has had its fullest movement. The valve-plug g thus performs two separate functions, the first being to relieve the pressuren of fluid from the upper valve while it is in operation and the second to enable the upper valve to be removed from the shell absolutely for purposes of repair or cleaning, the lower valve then holding or retaining the passage of the iiuid into the shell. The valvestem is operated by the movement of the upper or main valve, which moves in the valveseat of the principal-valve chamber, as already explained. The upper or main valve chamber, provided with the annulus c, adapted to engage the seat in the shell, is also constructed to form a conical valve-seat to engage with the conical valve b, provided with its stem b, which passes upward through the center of said valve-chamber, the said valvestem being provided with the lock or lug adapted to engage with a coperating lock or.

lug in the end of the motive stem. The said valve-chamber is constructed with a partition, as shown in Fig. l, the said partition dividing or separating the lower part of the valvechamber d' from the upper d2, through which the valve-stem operates, by which means the passing i'uid is checked in its passage below said partition at the moment of the iinal clousing of said valve, and the upper portion of said valve-chamber is provided with lateral ports a2, by means of which free egress is afforded for the iiuid passing from said valvechamber. The upper portion of said valve chamber or frame a is furnished with a seat to receive suitable packing c', adapted to prevent the passage of the fluid above said point outside the valve-chamber, and upon said packing rests the cup-shaped packing-disk e, adapted to be engaged by a couplingnut formed by the union of shells A and B, between which coupling-nut and the seat in the shell the main valve chamber is securely clamped. The said packing-disk e is further so constructed as to provide a passage for the actuating-stem, as shown, having a cylindrical passage th rough its center,in which said actuatingstem operates, said actuating stem or piston being maintained in its position by the spring interposed between the shoulder or cap atits top and the bottom of the cup-shaped packing-disk. It is obvious that when the stem of the conical valve is interlocked with the terminal of said actuating-stem the device is held firmly in said position and the movement downward of the actuating device will operate to open the valvefrom the mainvalve chamber. The upper portion of the main-valve chamber aifords sufficient space for the passage of the lock of the actuatingstem into said opening by lateral movement to engage withthe lock in the valvestem; but when returned to position thus locked the introduction of the combined devices into the cylinder of the shell renders impossible any lateral movement and consequently any unlocking of parts, as previously described.

I do not confine myself to the exact form of parts shown, as these may be modified without departing from the spirit of my invention.
